SPECIFICATION forming part of Letters Patent No. 605,404', dated June 7, 1,898.

Application filed October 16, 1897. Serial No. 655,413. (No model.)

To @ZZ whom, it may concern.- Y,

Be it known that I, JOHN EDWARD Davis, of Va-shington, in the county of Warren and State of New Jersey, have invented certain new and useful Improvements in Organs, of

certain new and useful improvements in or.

gans and like wind instruments whereby a proper actuating of the swells, mutes, couplers, and like parts is obtained without binding and undue friction of the moving parts caused by sidewise motion and shrinkage in any form.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointedI out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the improvement as applied and with part broken out. Fig. 2 is a cross-section of the same on the line 2 2 of Fig. 1. Fig. 3 is a reargelevation of the same, and Fig. 4 is a perspective view of the lever.

Each of the stops A is fitted to slide in the usual bearings in the organ-casing B, and each stop is provided with a guide C for preventing the stop from turning and for limiting the inward and outward movement of the stops when pulled or pushed by the organist. l

On each stop A, within the casing B, is arranged a pivot D, on which is hung a depending link E, guided in its lateral movement between the walls of a slot in the stop, as is plainly indicated in Figs. l and`2, the lower or free end of the said link being form ed with a fork E', straddling the pin Ff` of a lever F,

which constitutes the main portion of the im-Y provement. The lever F is made of a single piece of wire, with its pivot portion F2 formed at one end with an arm F3, carrying at its free forward end the aforesaid pin F', said pin standing parallel to the pivot F2. The

other end of the pin is formed vwith an arm F4, extending downward and upward at right angles to the arm F3, with a bend F5 termi nating in the end FG, arranged to carry a block G, connected by a link H with a mute, swell, coupler, or other part I, as indicated in the drawings. The end FG, carrying the block G, .is arranged in alinement with the link E and the stop A-that is, in the plane of movement of the lever F andthe said stopso that a central draft is obtained to insure a proper opening and closing of the mute, swell, coupler, or like parts and irrespective of shrinkage in the casing or other parts of the organ. It is understood thatby the peculiar arrangement of the arms F8 F4 and the location of the bend F5 the above result is ob tained.

The pivot portion F2 of the lever F is set in a bearing B', formed longitudinally in one of the rear walls of the casing B, the said bearing being in the form of a slot closed by a strip B', as is plainly indicated in Figs. 2 and 3.

Now when the swell, mute, coupler, or the like is in a normal position then the stop A. is in its innermost position, as indicated in full lines in Fig. 2, with FVthe link E extending forward, as shown. When the stop A is pulled outward, the link E presses on the pin F in a downward direction and imparts a swinging motion to the lever F, so that the arm F4 swings transversely in a rearward direction to pull on a link H and open the mute, swell, or coupler I, as indicated in dotted lines in Fig. 2. When the stop is pulled outward to its full extent, then the link E passes a eentralposition, as indicated in dotted lines in Fig. 2, so that when the organist releases the knob of the stop the several parts remain locked in this position. Vthen the organist pushes the knob of the stop inward, then the several parts return to their original position owing to the spring connected with the part to be actuated, the closing of the mutes or swells being gradual, as the link assumes its normal inclined position 'when the stop is pushed in.

Several connections between the stop and the part to be actuated are shown in the drawings, and one has been described, it being understood, however, that for making the connection between the lever and the part to be actuated various means besides the link H maybe employed. For instance, as shown IOO in the drawings, the lever F for the stop A' has its block G connected by a link Il with a lever J, connected by a link JWith aswell J 2, and the stop A2 has the block G of its lever F connected by a link K with a niute K', fulcrumed in the easing.

Now it will be seen that the lever F can be readily constructed and easily applied on an organ without requiring ninch litting by skilled Workmen.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An organ, provided with a lever formed with a pivot portion, and arms extending therefrom and at angles to each other, one of said arins having a bent portion extending parallel and in alineinent with said pivot portion and arranged Afor connection with the actuating part, and the other arin being formed with a bend by which it is brought in line with the center of the pivot portion, said latter arm being arranged lor connection with the part to be actuated, as set forth.

2. In an organ, the hereindescribed lever formed with a transversely-extending pivot portion held to rotate on its longitudinal axis in a bearing in the organ, an arin extending from one end of said pivot portion and at an angle thereto, said arm having its end bent parallel and in alinenient with the pivot portion and by which it is connected with the actuating part, and a second arm extending from the opposite end of said pivot portion and at an angle thereto, said second arln being formed with a bend by which it is brought in line With the Center of the pivot portion and being arranged lfor connection with the part to be actuated, as set forth.

8. In an organ, the combination with a frame and a stop iitted in said frame and l1aving a link pivoted thereon, of a lever formed of a single piece of wire bent to `forni a transverse pivot portion mounted to rotate on its longitudinal axis in a bearing in said `frame and having its center in line with said link, and two arms extending in opposite direc tions from the ends of said pivot portion and at an angle thereto, one of said arms being provided with a pin extending parallel with said pivot portion and arranged Alor conneetion with said link, and the other arm having its end bent in line with the center of said pivot portion and arranged for eonnection with the part to be actuated, as set forth.
